Had the blue screen again this morning after unlocking the phone with my code ( don't use fingerprint) and pressing the mail icon. This time though was the first time I've seen vertical red lines across the screen.
This is happening to me with ESPN Scorecenter and with Numbers
I posted a video

I find it odd that its happening with numbers since it's an Apple app. And I had the phone replaced but still having the same problem with the replacement. full story here:

It's happening with lots of apps, not just the iWork ones, I had it this morning just by unlocking the phone and opening safari.
